CAPE-OPEN

My question is regarding the input/output parameters in COCO custom models, e.g., SciLab or MATLAB CAPE-OPEN Unit Operations. Is there any way to define a parameter as a vector with its size being the number of components? For example, in a membrane module you may need to ask the user to enter permeance, which is defined per component and you don't know in advance how many components exist (so you don't know how many scalar parameters you should define).
As an alternative, is it possible to define such parameters as a new property in the thermo package (so it is automatically populated for every component)?
Any solution or workaround to this issue would be appreciated!

The parameters that are exposed by a property package, that is up to the property package. Apart from that parameter support for property packages is virtually non-existent.

If you want to automatically populate all unit operations of your particular type, I suppose you can have machinery that is specific to your unit operation (perhaps a centrally located data file with data for all compounds?).

The Scilab CAPE-OPEN unit operation currently does not allow for exposing array parameters. Can you illustrate how you would use such a parameter? Is it just so that the user can change it?

Glad to hear it works.
